While gas springs and hydraulic dampers, specialized types of springs that utilize gas under compression to exert force, are designed in different sizes and lengths, selecting one depends on two main factors, the necessary spring force as well as the effective stroke of the spring. Application design considerations from the gas springs involves selecting springs with the proper sized cylinder and piston based on the force required for the application. As an example, the trunk lid of your car is based on two gas springs on each side with the lid, that if compressed create a force that is roughly comparable to the load of the lid. Similarly for an desk chair, the force made by the gas lift ought to be somewhat higher compared to weight from the chair, allowing the consumer to effortlessly move the chair up and down. Furthermore, to stop buckling the buckling with the gas springs, the force produced should invariably be consistent with its centerline, designed for a strut bracket.


Another factor to consider while selecting or designing a gas spring will be the ambient operating temperature, as both extreme cold and warm temperatures modify the operation. The alteration in temperature affects the pressure that the gas spring can exert and therefore the output force. At very high temperatures, the seal permeability increases and gas molecules may escape from the seal easier. They are also designed in line with the performance guidelines that include cold closing and opening efforts, hot closing and opening efforts, self-rise and self-close angle, hump, 70 degrees, and damping.

Resistance to dents, damage, and abrasion also need to be ensured while designing the cylinder and also the piston. Special features, for example external locking and variable damping, also need to be considered. Aspects another major ingredient that is highly recommended while producing gas springs. As an element of this factor, the suitability with the spring and the mounting position strength are considered. Additionally, a second locking mechanism can be incorporated for safety purposes, if needed.

While mounting a gas spring, care needs to be taken to make certain that they may be mounted in an upright fashion with all the piston rod pointed downwards. This can be to ensure the rod seal is kept lubricated at all times. When the spring is to be mounted at an angle, care ought to be taken up be sure that the amount of the lubricating oil is sufficient for the rod seal being always lubricated through the operation.
